ZipEnable

Enable Native HTTP
Compression on IIS6

Speed Up Your Web Sites

Unlock and Extend the Native Compression Features in IIS 6.0

HTTP compression speeds up file delivery, reduces bandwidth costs, and reduces server load. ZipEnable extends the built-in "On/Off" compression in IIS 6.0. The native compression is fast, incurs minimal resource penalties, and is included in the purchase of the OS.

However, there are drawbacks to the built-in tools:

Without ZipEnable:

No browser compatibility checking. Without this feature, you risk sending compressed content to a browser incapable of decompression.

Modify Compression Schemes by File Type

Using Industry-standard Gzip and Deflate compression schemes, ZipEnable modifies compression schemes by file type. Ability to set level of compression (1-10) for each scheme and access to granular control of acceptable file extensions for compression.

Persistent Overrides

Compression Exclusions

ZipEnable is able to control compression exclusions based on HTTP version, proxy usage, and type of request.

Gzip and Deflate Compression

Within ZipEnable user has ability to set priority of default Gzip and Deflate compression schemes. As well as, adjust other compression settings such as I/0 buffer size and minimum file size to compress limits.

CPU Roll-off option

ZipEnable can automatically dial back compression rates for periods of unusually heavy traffic to guarantee that compression does not overwork your CPU. ZipEnable enables the user to configure CPU utilization threshold for compression roll-off.

The current version of ZipEnable does not support scenarios in which IIS application pools are running in 32-bit mode on 64-bit hardware. Please contact Port80 Software Technical Support for additional information.
